Abstract
An antenna module,of the present invention comprises a wire first dipole antenna arm,oriented in a first direction and a wire second dipole antenna arm,oriented in a second direction that is perpendicular to the first direction, said two arms being respectively electrically connected to a printed circuit board,at two points, and a gap G being formed between the two points. Said two antenna arms are interfaced to the associated transmitting/receiving circuitry by a coaxial cable,. Values of the length of the two arms, the length of the gap, the diameter of each arm, an impedance of the coaxial cable, and an operating frequency range are chosen to obviate the need for matching circuitry to perform the functions of transfer, balancing and matching between the first and second dipole antenna arms. Therefore, the antenna module is simplified and can be placed compactly at a corner of the portable computer to provide improved performance.
